Bilateral Peripheral Infiltrative Keratitis After LASIK

To report a case of peripheral infiltrate between the flap edge and limbus, which appeared on the first postoperative day after laser in situ keratomileusis (LASIK).A 22-year-old man underwent uneventful bilateral simultaneous LASIK but developed a thick band of infiltrate between the flap margin and limbus extending from 2 o'clock to 9 o'clock in both eyes. The flap edge was not involved. The infiltrate was more concentrated at the periphery and faded centrally and progressed diffusely into the interface leading to typical diffuse lamellar keratitis.The infiltrate responded to topical prednisolone acetate 1% eye drops.This entity was referred to as LASIK-induced bilateral peripheral infiltrative keratitis with a probable immune-mediated etiology.
